WEBVTT 00:00:00.000 --> 00:00:05.602 align:middle line:90% 00:00:05.602 --> 00:00:07.310 align:middle line:84% We have been looking at, then, how we can 00:00:07.310 --> 00:00:08.930 align:middle line:90% do motion capture of musicians. 00:00:08.930 --> 00:00:10.910 align:middle line:84% But another group of people that's 00:00:10.910 --> 00:00:12.440 align:middle line:84% interesting to do motion capture of 00:00:12.440 --> 00:00:16.550 align:middle line:84% is perceivers, or audiences, or people that experience 00:00:16.550 --> 00:00:17.893 align:middle line:90% music in different ways. 00:00:17.893 --> 00:00:20.060 align:middle line:84% And this is something that you have experience with, 00:00:20.060 --> 00:00:23.600 align:middle line:84% Victor, both in capturing audiences, 00:00:23.600 --> 00:00:27.276 align:middle line:84% like in the library setting where we were, 00:00:27.276 --> 00:00:31.940 align:middle line:84% or also even capture audiences in the lab. 00:00:31.940 --> 00:00:33.620 align:middle line:84% And what are some of the challenges 00:00:33.620 --> 00:00:38.810 align:middle line:84% when you're capturing audiences with motion capture? 00:00:38.810 --> 00:00:41.850 align:middle line:84% Well, when capturing audiences in venues, 00:00:41.850 --> 00:00:43.490 align:middle line:84% so there are many other challenges 00:00:43.490 --> 00:00:46.200 align:middle line:84% that have to do with the practicalities of the place. 00:00:46.200 --> 00:00:48.230 align:middle line:84% So to look at the systems, to not 00:00:48.230 --> 00:00:51.960 align:middle line:84% interfere with the experience of the concert or the performance. 00:00:51.960 --> 00:00:53.450 align:middle line:84% So audiences are not used to being 00:00:53.450 --> 00:00:54.980 align:middle line:90% part of experiments normally. 00:00:54.980 --> 00:00:57.450 align:middle line:84% So they normally adapt their behaviour. 00:00:57.450 --> 00:00:59.430 align:middle line:84% So you have to be aware of that as well. 00:00:59.430 --> 00:01:02.150 align:middle line:84% So we have to limit how much we affect the experience, 00:01:02.150 --> 00:01:04.099 align:middle line:84% because we want them as natural as possible. 00:01:04.099 --> 00:01:06.908 align:middle line:84% So we call that ecology, making the experiment 00:01:06.908 --> 00:01:08.450 align:middle line:84% as ecological as possible, so that we 00:01:08.450 --> 00:01:12.077 align:middle line:84% get what we want, the pure reactions from the audience. 00:01:12.077 --> 00:01:13.910 align:middle line:84% So there are many challenges, both practical 00:01:13.910 --> 00:01:16.535 align:middle line:84% and also theoretical, on how to do this properly. 00:01:16.535 --> 00:01:18.410 align:middle line:84% And that's different when we do it in the lab 00:01:18.410 --> 00:01:21.860 align:middle line:84% and when we have just perceivers in a lab. 00:01:21.860 --> 00:01:23.560 align:middle line:84% They also know it's an experiment. 00:01:23.560 --> 00:01:24.980 align:middle line:90% So it's also challenging. 00:01:24.980 --> 00:01:26.480 align:middle line:84% But the settings are more controlled 00:01:26.480 --> 00:01:29.540 align:middle line:90% than compared to a venue. 00:01:29.540 --> 00:01:33.290 align:middle line:84% So the setup on the cameras and things are kind of the same, 00:01:33.290 --> 00:01:34.960 align:middle line:84% but it's more about everything else. 00:01:34.960 --> 00:01:35.460 align:middle line:90% Yeah. 00:01:35.460 --> 00:01:35.960 align:middle line:90% I guess. 00:01:35.960 --> 00:01:38.870 align:middle line:84% An environment and they feel in lab, or like they 00:01:38.870 --> 00:01:40.320 align:middle line:90% feel they are in an auditorium. 00:01:40.320 --> 00:01:43.700 align:middle line:84% So when they're in the concert, they are there to enjoy. 00:01:43.700 --> 00:01:46.790 align:middle line:84% And so we don't want to interfere with that 00:01:46.790 --> 00:01:49.960 align:middle line:84% or to affect that experience, when in a concert. 00:01:49.960 --> 00:01:51.710 align:middle line:84% But you have also been running experiments 00:01:51.710 --> 00:01:53.870 align:middle line:84% with people where it's more controlled. 00:01:53.870 --> 00:01:56.570 align:middle line:10% And one particular type of experiment paradigm 00:01:56.570 --> 00:01:59.480 align:middle line:10% that you have been working with is people standing still. 00:01:59.480 --> 00:02:04.550 align:middle line:10% And what have you done then? 00:02:04.550 --> 00:02:06.680 align:middle line:84% Yeah, we ask people to stand as still as 00:02:06.680 --> 00:02:12.410 align:middle line:84% possible while we will play music or sounds in the lab. 00:02:12.410 --> 00:02:16.970 align:middle line:10% And they stand in groups together in the lab. 00:02:16.970 --> 00:02:18.692 align:middle line:84% And it's always counterintuitive. 00:02:18.692 --> 00:02:20.900 align:middle line:84% So we're not used to standing still for long periods, 00:02:20.900 --> 00:02:22.550 align:middle line:84% or at least we try to avoid those. 00:02:22.550 --> 00:02:25.050 align:middle line:84% Like queuing is uncomfortable, for example. 00:02:25.050 --> 00:02:27.620 align:middle line:84% So we just want them to stand there in silence and as 00:02:27.620 --> 00:02:28.980 align:middle line:90% still as possible. 00:02:28.980 --> 00:02:31.220 align:middle line:84% So it's not something that we're used 00:02:31.220 --> 00:02:34.160 align:middle line:84% to do, so it's challenging for many of them, for many people. 00:02:34.160 --> 00:02:36.230 align:middle line:84% And also the fact that then there 00:02:36.230 --> 00:02:40.200 align:middle line:84% is this music part coming in and playing, so we have 00:02:40.200 --> 00:02:44.060 align:middle line:84% had participants who are unable to not move to music, 00:02:44.060 --> 00:02:47.460 align:middle line:84% that they just want to dance, if the music is too danceable. 00:02:47.460 --> 00:02:49.940 align:middle line:84% But the challenges remain and we want 00:02:49.940 --> 00:02:52.070 align:middle line:84% them to forget that this is, as possible, a lab, 00:02:52.070 --> 00:02:55.130 align:middle line:84% that they just standing as naturally as possible, 00:02:55.130 --> 00:02:59.480 align:middle line:84% and that they don't instinctively move to, 00:02:59.480 --> 00:03:00.980 align:middle line:84% or they instinctively move to music, 00:03:00.980 --> 00:03:02.450 align:middle line:84% but not because they want to dance, 00:03:02.450 --> 00:03:04.040 align:middle line:84% but because it's kind of-- you know, 00:03:04.040 --> 00:03:05.600 align:middle line:90% it helps to move to music. 00:03:05.600 --> 00:03:08.360 align:middle line:84% So this is kind of the challenges that we want to face 00:03:08.360 --> 00:03:10.850 align:middle line:84% and we are trying to deal with now here 00:03:10.850 --> 00:03:14.540 align:middle line:84% with these statistical data set and the experiments. 00:03:14.540 --> 00:03:17.840 align:middle line:84% We want participants to experience music, 00:03:17.840 --> 00:03:20.330 align:middle line:84% and we want to know what it does naturally to the bodies. 00:03:20.330 --> 00:03:22.370 align:middle line:84% So for that we need them to forget that they are 00:03:22.370 --> 00:03:24.558 align:middle line:90% being measured, for example. 00:03:24.558 --> 00:03:26.850 align:middle line:84% Is it really possible to capture people standing still? 00:03:26.850 --> 00:03:28.880 align:middle line:84% I mean these must be very small movements. 00:03:28.880 --> 00:03:30.410 align:middle line:90% Yeah, they're minuscule. 00:03:30.410 --> 00:03:33.320 align:middle line:84% But we never are completely still. 00:03:33.320 --> 00:03:37.010 align:middle line:84% We breathe, our heartbeats, we have to accommodate a posture 00:03:37.010 --> 00:03:38.940 align:middle line:90% if we stand for longer periods. 00:03:38.940 --> 00:03:41.067 align:middle line:84% So there's always these movements that occur. 00:03:41.067 --> 00:03:42.650 align:middle line:84% So on top of that, there is a movement 00:03:42.650 --> 00:03:45.050 align:middle line:84% that we have measured that occurs because of the music, 00:03:45.050 --> 00:03:47.032 align:middle line:84% or apparently because of the music. 00:03:47.032 --> 00:03:48.740 align:middle line:84% So on top of these natural movements that 00:03:48.740 --> 00:03:50.157 align:middle line:84% happen when we are standing still, 00:03:50.157 --> 00:03:51.883 align:middle line:84% there is something else that's happening 00:03:51.883 --> 00:03:53.300 align:middle line:84% when the music is being presented, 00:03:53.300 --> 00:03:55.520 align:middle line:84% and that's what we're trying to understand. 00:03:55.520 --> 00:03:58.550 align:middle line:84% And you've been measuring people's head motion, 00:03:58.550 --> 00:04:00.740 align:middle line:84% you've been putting a marker on the head 00:04:00.740 --> 00:04:03.047 align:middle line:84% and then you see people swaying and things. 00:04:03.047 --> 00:04:04.880 align:middle line:84% But then again that's on a very small scale. 00:04:04.880 --> 00:04:05.380 align:middle line:90% Yeah. 00:04:05.380 --> 00:04:07.037 align:middle line:84% Yeah, I mean, it's because the marker 00:04:07.037 --> 00:04:08.120 align:middle line:90% is on the top of the head. 00:04:08.120 --> 00:04:09.540 align:middle line:90% So we see mostly head sway. 00:04:09.540 --> 00:04:12.618 align:middle line:84% But it's still minuscule, unless they really 00:04:12.618 --> 00:04:13.910 align:middle line:90% change the posture of the head. 00:04:13.910 --> 00:04:15.500 align:middle line:84% But they know they are being recorded. 00:04:15.500 --> 00:04:16.610 align:middle line:84% They know they have to stand still. 00:04:16.610 --> 00:04:17.930 align:middle line:90% So they normally don't do it. 00:04:17.930 --> 00:04:20.390 align:middle line:90% They don't do gross motions. 00:04:20.390 --> 00:04:22.730 align:middle line:84% So it's normally very small, and we 00:04:22.730 --> 00:04:26.480 align:middle line:84% have to really dig in to find what, when, where was the music 00:04:26.480 --> 00:04:28.370 align:middle line:90% influencing this movement. 00:04:28.370 --> 00:04:29.950 align:middle line:84% And then we have collected this also, 00:04:29.950 --> 00:04:31.850 align:middle line:84% in this Oslo standstill database, right? 00:04:31.850 --> 00:04:32.090 align:middle line:90% Yeah. 00:04:32.090 --> 00:04:33.550 align:middle line:84% It's actually hundreds of recordings. 00:04:33.550 --> 00:04:35.070 align:middle line:84% Yeah, we have done it for several years now. 00:04:35.070 --> 00:04:36.737 align:middle line:84% And every year we have 100 participants. 00:04:36.737 --> 00:04:39.410 align:middle line:84% So we have like 600 people's data 00:04:39.410 --> 00:04:42.590 align:middle line:84% on how they moved their body, when 00:04:42.590 --> 00:04:44.130 align:middle line:90% they are trying not to move. 00:04:44.130 --> 00:04:46.100 align:middle line:84% So it's quite interesting and it's also 00:04:46.100 --> 00:04:48.020 align:middle line:84% interesting to see what people will do with this database 00:04:48.020 --> 00:04:50.353 align:middle line:84% in the future, because it will be available for everyone 00:04:50.353 --> 00:04:53.570 align:middle line:90% to try and play with this data. 00:04:53.570 --> 00:04:56.840 align:middle line:84% OK, so, as you hear, there are many different types 00:04:56.840 --> 00:04:58.400 align:middle line:84% of things to think about when you 00:04:58.400 --> 00:05:02.750 align:middle line:84% are doing motion capture of audiences or perceivers, 00:05:02.750 --> 00:05:04.400 align:middle line:84% whether it's people standing still, 00:05:04.400 --> 00:05:07.910 align:middle line:84% or people sitting in an audience or moving around. 00:05:07.910 --> 00:05:11.360 align:middle line:84% So that's also related to whether you are working 00:05:11.360 --> 00:05:12.700 align:middle line:90% in the lab or outside the lab. 00:05:12.700 --> 00:05:15.540 align:middle line:84% So it's not really anything that you can say is right or wrong. 00:05:15.540 --> 00:05:17.832 align:middle line:84% It's just different in a way, and many different things 00:05:17.832 --> 00:05:19.660 align:middle line:90% to think about. 00:05:19.660 --> 00:05:27.062 align:middle line:90%
